Abnormally strong sense of smell for a bird? 0_0

[Cephillion]

This morning I brought out a packet of sunflower seeds. As usual, Cassiel was with me.

When he saw the packet, he went slightly hyperish. xD He immediately jumped onto the packet and began nibbling on it.
I thought, "Oh, nevermind, maybe he just wants to chew it," since he does that often.

Then I opened the packet (carefully avoiding Cassiel in the process of course) and brought out a smaller bag of seeds. Instantly Cassiel switched his attention to that bag. I showed him the bigger packet in case he wanted to chew on it - he just stared at it and even cowered a little. He went to the smaller bag and tried to open it.

So then, I opened it, then he went a little beserk, picking at the seeds.

From his behaviour, well...do you think he might have an abnormally strong smell, or just have a sixth birdie sense for food?

He probably recognized the bag. xD Birds are far from stupid-- if he's seen you bring out food from there before, that's probably it.

I've brought it out a few times before. xD That should explain it, though the times I did bring them out were about quite some months apart.
